A Power Network Craftsperson has responsibility for the safe construction, maintenance and repair of the UK’s electrical power network, to provide a safe and reliable supply of electricity to the country. This involves working at various locations across a company’s power network. The occupation exists within an industry with a high level of safety critical activities, so there is a requirement for a disciplined and responsible approach to work. The work requires a good level of physical ability in order to access and egress work positions at height.
Individual employers will set the selection criteria. Apprenticeship candidates will normally have attained 3 to 5
GCSEs at grades A to C (including mathematics, English and a science), or equivalent qualifications.
There are three specialisms within this occupation: working on overhead lines, on underground cables and in substation fitting. A successful apprentice will have met the core requirements and also one of the specialism requirements below.
